Estimates only. These calculators are for education, not a loan estimate, tax bill, or legal advice. Your lender’s Loan Estimate, your closing agent’s settlement statement, and the St. Lucie County Property Appraiser are the final word. Figures are calculated in your browser; nothing you type is sent anywhere.

How this is calculated

Principal and interest use the standard fixed-rate formula: payment = loan × r ÷ (1 − (1 + r)−n), where r is the monthly rate and n is the number of payments. Taxes and insurance are divided by 12. Mortgage insurance is the annual rate × the loan amount ÷ 12, and in real life it can drop off or change; ask your lender.

Private mortgage insurance is usually required on a conventional loan with less than 20% down (CFPB). Compare lender quotes on the official Loan Estimate form (CFPB).
